Answer: He will travel 21 km in 35 minutes.
Explanation:
To find the number of miles he will travel in 35 minutes, we can set up a proportional relationship as follows:
36 → kilometers ? → kilometers
----- = -----
60 → minutes 35 → minutes
Next, you cross multiply 36 X 35 = 1260 and divide 1260 ÷ 60 = 21 to get 21 km in 35 minutes.
